Perioperative parenteral tranexamic acid in liver tumor resection: a prospective randomized trial toward a "blood transfusion"-free hepatectomy.
OBJECTIVE: To examine the feasibility of a real "blood transfusion"-free hepatectomy in a large group of patients with liver tumors. SUMMARY BACKGROUND DATA: Bleeding control and blood transfusion remains problematic in liver resection. A real "blood transfusion"-free hepatectomy in a large group of patients has rarely been reported. The impact of tranexamic acid (TA), an antifibrinolytic agent, on blood transfusion in liver resection is unknown. METHODS: A prospective double-blind randomized trial was performed on elective liver tumor resections. In group A, TA 500 mg was intravenously administered just before operation followed by 250 mg, every 6 hours, for 3 days. In group B, only placebo was given. The patients' background, blood transfusion rates, and early postoperative results in the 2 groups were compared. Factors that influenced blood requirement were analyzed. RESULTS: There were 108 hepatectomies in group A and 106 hepatectomies in group B. The patients' backgrounds, operative procedures, and hepatectomy extent did not significantly differ between the 2 groups. Although the differences of the operative morbidity and postoperative stay were not significant, a significantly lower amount of operative blood loss, lower blood transfusion rate, shorter operative time, and lower hospital costs were found in group A patients. No patient in group A received blood transfusion. No hospital mortality occurred in either group. Tumor size and use of TA were independent factors that influenced blood transfusion. CONCLUSIONS: Perioperative parenteral use of TA reduced the amount of operative blood loss and the need for blood transfusion in elective liver tumor resection. A real "blood transfusion"-free hepatectomy may be feasible with the assistance of parenteral TA.[1]References
